Description CH flow High temperature C.H. return Low temperature C.H. return Smoke chamber Chimney connection Burner Progressive smoke pipes Condensate drain Boiler drain The KDE range is constituted by a strong outer shell, inside which it is present, in the upper part, a blind cylindrical furnace, in which the central burner flame reverses peripherally toward the front. From here, the combustion gases are carried, through the special workmanship of the door insulation, in the pipes of the third pass, to reach the rear smokes chamber, where the drain of the condensate takes also place, for going then to the chimney. The guided run of the water inside the body allows to exploit at the maximum the thermal exchange surfaces and to balance uniformly the thermal and mechanical stresses on the materials. The tube bundle, horizontally placed in the lower part of the body, is composed of stainless steel pipes in AISI 316L and special multi-fin inserts in Aluminium, particularly effective in the transfer of the heat to the water, favouring the condensation of the smokes. The tube bundle is slightly tilted toward the smoke chamber for: natural outflow of the condensates, absence of wet acidic deposits and cleaning, for gravity, of the exchange surfaces. The driven run of the combustion gases allows to exploit at the most the thermal exchange surfaces and to balance uniformly the stresses on the materials, both thermal and mechanical. The two connections of high/low return temperature reduce the hydraulic interferences, exalting the efficiency. The upper part of the outer shell is equipped with hooks for lifting the boiler.

Details Special smoke pipes Characterized by: a circular section, in stainless steel AISI 316L, containing a series of multi-radial aluminium fins armoured elements, assembled in just one piece progressive density of the aluminium fins with an opportune initial flaring, to make easy the cold starts. Placed in the tube bundle, favour: exceptional thermal exchange functional outflow of the condensate absence of wet acidic deposits washout, for gravity, of the smooth exchange surfaces greater duration. Multi-radial aluminium fins External pipe in stainless steel AISI 316L External pipe of 57 diameter, that contains an aluminium multi-fin extruded portion, assuring a very high heat exchange and resisting to the condensate. Hydrodynamic structure of the outer shell Characterized by: classical structure of flame inversion type and second smoke pass 8 type shape, with the pipes far away from the lowest part, in order to avoid incrustations thermal exchange maximization, mainly in the low temperature return outer shell insulated with a mineral wool mattress, 100 thick, protected by an anti tearing fabric water runs driven and braked inside the body the low smoke side resistance, (50 Pa = ca. 5 w.g.) guarantees an excellent operational silentness and the possibility to work in combination with the most coon burners in order to have an easy smoke evacuation. Smart hydraulic connection Complete differentiation of the connection points of the two C.H. returns of high and low temperature. The high temperature return is positioned in the middle part of the upper outer shell, in contact with the furnace cylinder (hotter) The low temperature return is connected in the lowest part, where the tube bundle is present and favours the condensation effect. Door features The insulation of the door is in recyclable super light refractory cement: high insulating capacity lighter and more resistant than the conventional products Closing of the door with precise adjustability: selfcentering reversible (with opening to the right or to the left) adjustable: in vertical, transversal and axial direction.
